Video has been released in the case of two Bay Area men who were shot and killed last week while attempting a robbery.

The East Bay Times reports that Ellis Williams, 38, and Joseph Brooks, 32, both of Antioch, were each shot at least once when they tried to enter a home at approximately 11:15 p.m. on June 21. The homeowner was armed and shot and killed both men.

They were pronounced dead at the scene.

In the grainy black and white video, two men can be seen entering the back of a home. They can be seen through the window and then there are two flashes of light as the homeowner opens fire. The men run out the door as they are shot at again.

Brentwood police lieutenant Walter O’Grodnick told the East Bay Times that at least one of the robbers had a gun and presented a threat to the homeowner. While police detained the shooter for questioning it is believed the double homicide was justifiable and he was not arrested.

The homeowner has not been identified.

According to NBC Bay Area, initial investigation showed the two men were planning a targeted home invasion. When the suspects confronted the homeowner, he opened fire.

A neighbor told The Mercury News that he saw a strange car nearby that took off after the shooting. It is unclear as to if that car had anything to do with the attempted robbery.

Brentwood has a low crime rate compared to its other East Bay neighbors. The last homicide in Brentwood was a murder-suicide in 2012.
